Inventor: ODENWALDER JOSEPH P
IPC: H04J13/00
Filed: 1997-06-09
Granted: 2007-06-05
Abstract: Method and apparatus for high rate CDMA wireless communication in which a set of individually gain adjusted subscriber channels are formed via the use of a set of orthoganol subchannel codes (W1) having a small number of PN spreading chips per orthogonal wave form period. Data to be transmitted via one of the transmit channels is low code rate error correction encoded (134) and sequence repeated before being modulated with one of the subchannel codes, gain adjusted (152, 154, 156, 158), and summed (160) with data modulated using the other subchannel codes. The resulting summed data is modulated using a user long code and a pseudorandom spreading code (PN code) and upconverted for transmission.

Title: Method for identifying compounds affecting rna/rna binding protein interactions
Inventor: GIORDANO TONY
IPC: G01N33/53
Filed: 1997-07-31
Granted: 2007-07-10
Abstract: It has been discovered that a single set of conditions can be used to detect nearly every interaction of RNA binding proteins and RNA molecules. Prior to this discovery it was thought that each specific interaction required separate optimized conditions in order to be detected. Assays employing the disclosed universal conditions are useful for identifying RNA binding proteins that interact with specific RNA molecules of interest, detecting RNA molecules that interact with specific RNA binding proteins of interest, identifying RNA binding proteins active in certain cell types and under certain physiological conditions, identifying specific regions of an RNA molecule that interact with RNA binding proteins. Screening assays employing the disclosed universal conditions are useful for identifying compounds that modulate RNA/RBP interactions of interest.

Abstract: An integrated water distribution network supplies the requirements of both domestic and fire sprinkler water fixtures in a dwelling structure. The network includes a plurality of multiport fittings which are interconnected together with flexible conduits. A conventional fire sprinkler is also coupled to the multiport fittings. The network is supplied water by a plurality of water supply lines which originate at a manifold. Individual water fixtures are connected to the distribution system through flexible lines.      During use of a water fixture, water flow through essentially the entire system is established. The distribution system can thus be characterized as a "nonstagnant" water network.
